Texas Rat Snake (Elaphe obsoleta subsp. lindheimeri: Colubridae) A non venomous species. Adults range from 107-183 cm (42-72 in) with a record of 215.3 cm (84.75 in). This specimen was definitely on the large end of its range. Camelot Park, Bryan, Texas, USA. Open park setting with scattered oaks, pecan and juniper with some woodlands and a small flower garden at ca. 94 m (310 ft) elevation. I was walking back to where I had parked and looked up and this snake was crossing the wide path in front of me. The creek was only a few meters to its rear and an open park with scattered trees in front of it. I was curious to see where it was going to go and I wanted to make sure no one hurt it, at least while I was there. See next picture.
